Best used for
- Median and roundabout massing with oleander and bougainvillea
- Industrial and institutional boundary planting
- Quick colour on new sites — it performs in the first season
- Slope and embankment stabilising alongside vetiver
Flowering shrub
Yellow Bells (Tecoma)
A tough yellow-flowering shrub that blooms almost continuously in Indian heat — the standard companion to oleander and bougainvillea on medians and roundabouts.
About Yellow Bells (Tecoma)
Tecoma stans provides the yellow in the standard Indian median palette. It flowers hard, recovers from hard pruning, tolerates poor soil and dust, and reaches useful size in its first year, which makes it the shrub of choice when a corridor needs to look planted before an inspection.
It is a fast, cheap, disposable performer rather than a long-term structural plant. Left unpruned it becomes woody and leggy at the base within three years; cut back hard each spring it stays dense and flowers for most of the year. Write that cycle into the maintenance scope or it will disappoint by year three.
One caution worth stating plainly: Tecoma stans seeds prolifically and behaves invasively in several tropical regions. Keep it away from protected areas, forest margins and water bodies, and remove seed pods on ornamental installations where volunteers are a nuisance.
Do not use where
- Fine ornamental gardens where its self-seeding becomes a weeding load
- Locations near protected natural areas — it seeds freely and is invasive in some regions
- Deep shade

Care
Season-by-season care calendar
| Season | What to do |
|---|---|
| February–March | Hard prune to a low framework before the main flowering season. This is the cut that determines the year. |
| April–June | Peak flowering. Minimal irrigation once established. |
| July–September | Trim to control size and remove seed pods. Growth is fastest now. |
| October–January | Light shaping. Watch for cold damage in North India. |
Troubleshooting
Common problems and what causes them
| Symptom | Cause | Fix |
|---|---|---|
| Woody, bare-based plants after two or three years | No hard annual pruning | Cut back to 300–400 mm in February. It regenerates fully; skipping this makes the planting look derelict. |
| Seedlings coming up across beds and paving joints | Prolific seeding | Remove pods before they dry, and treat volunteers during routine weeding. |
| Poor flowering | Shade or excessive nitrogen | Full sun and lean soil. Do not include it in a fertilised lawn zone. |

flowering shrubs
Oleander (Kaner)
Nerium oleander
The standard Indian median shrub: continuous flowering, near-total drought tolerance, immunity to vehicle pollution — and toxic in every part, which decides where it can go.
- Height2–4 m unpruned; held at 1–1.2 m on medians
- WaterLow
- MaintenanceLow
flowering shrubs
Bougainvillea
Bougainvillea glabra / spectabilis
The hardest-working colour plant in India: months of bract colour on almost no water, provided you resist the urge to feed and irrigate it.
- Height1 m clipped, 3–4 m as a shrub, 8 m+ as a climber
- WaterLow. Over-watering is the single commonest cause of a green, flowerless plant
- MaintenanceModerate
lawns and groundcovers
Vetiver
Chrysopogon zizanioides
The engineering plant of Indian landscapes: a deep-rooted clumping grass that holds embankments, filters runoff and stops erosion where nothing else will grow.
- Height1–1.5 m clump; trimmed to 300–500 mm in ornamental use
- WaterLow once established
- MaintenanceLow
palms
Silver Date Palm
Phoenix sylvestris
India’s native date palm and the toughest formal palm available: silver-blue crown, diamond-cut trunk, indifferent to heat, drought, dust and cold.
- Height10–15 m mature
- WaterLow once established
- MaintenanceLow
Yellow Bells (Tecoma) — frequently asked questions
How tall does Tecoma stans grow?
Four metres if left alone. On medians it is held at 1–1.5 m with an annual hard prune plus one mid-season trim.
Is Tecoma the same as Tabebuia?
No, though both are Bignoniaceae with trumpet flowers. Tecoma stans is a shrub; Tabebuia is a tree. Nurseries occasionally confuse the names.
Does Tecoma flower all year?
Close to it in the plains — flushes from February to November, pausing only in the coldest weeks and briefly after hard pruning.
